Early to bed and early to rise: Study suggests it's keeping kids leaner: Researchers recording the bedtimes and wake times of 2,200 Australian youths found that the night owls were 1.5 times more likely to become obese than the early birds, twice as likely to be physically inactive and 2.9 times more likely to sit in front of the TV and computer or play video games for more hours than guidelines recommend.
